Abstract: Several guidelines on the management of tuberculosis exist. They are considered a very good starting point for treatment, but not the only option, especially in cases of lung complications. Surgical treatment of these complications still may be challenging. We report the surgical strategy adopted to avoid thoracoplasty in a 38-year-old Bangladesh patient with bilateral cavitary pulmonary tuberculosis, complicated by a right empyema with bronchopleural fistula (BPF). After 6 months of proper medical treatment and surgical drainage of the right pleural cavity to achieve lung re-expansion, pleural decortication was attempted. Due to the persistence of chronic BPF and to the incomplete expansion of the lower and middle lobe, we decided to perform an open-window thoracostomy (OWT) instead of major surgery on the chest wall. This approach was preferred to a major lung resection, because of the increased surgical risks caused by inflammatory process around pulmonary vessels and the persistent pleural cavity infection. We achieved the intrathoracic infection resolution but not the BPF repair. Thus, the final step of the treatment consisted in closing both the BPF and the OWT with a myocutaneous pedicled flap of the rectus abdominis muscle. This decision was made to avoid disabling surgery of the chest. This case suggests that intrathoracic muscle transposition (IMT) may be an effective option to control BPF and residual thoracic cavity in chronic tuberculous empyema avoiding permanent open-window thoracostomy and thoracoplasty. The patient recovered well having an uncomplicated postoperative course.

Tuberculosis (TB) still remains a global health emergency even in developed Countries, and surgical management of tuberculous empyema and lung complications may be challenging (1). Several guidelines are available, but these cannot address every possible situation. Thus, the ideal strategy of tuberculous empyema with pulmonary complications is not yet well established (2). When other treatment fails, permanent open-window thoracostomy (OWT) and thoracoplasty are the two main options, carrying different impact on the patient’s quality of life and disabilities. According to our experience, the myocutaneous pedicled flap may be considered an effective alternative for the treatment of chronic tuberculous empyema with bronchopleural fistula (BPF) avoiding permanent OWT or thoracoplasty.

Most common cases present in literature describe OWT followed by intrathoracic muscle or omental transposition [e.g., (3-6)]. Usually intrathoracic muscle transposition (IMT) is performed with latissimus dorsi muscle, serratus anterior muscle or pectoralis major muscle, seldom the rectus abdominis muscle is used [e.g., (7-9)]. In our case, the latissimus dorsi muscle was already damaged and so ipovascularized by the previous thoracotomy, and other muscles were unusable because of their thickness. Thus, we used a myocutaneous pedicled flap of the rectus abdominis muscle: it could be removed with minimal loss of function as the posterior rectus sheath was strong enough to prevent an abdominal hernia.

We present the following article in accordance with the CARE reporting checklist.

Case presentation

A 38-year-old male from Bangladesh, with no significant medical history in the past was admitted to our hospital for persistent haemoptysis and cough with purulent sputum in the past 3 months (Figure 1). On a physical examination, he was in poor general conditions, feverishness, underfed and complaining dyspnoea. A Thorax CT-scan showed a right hydropneumothorax associated with a 6.5 cm cavitary lesion of the right upper lobe, with many other small contralateral cavitary lesions (Figure 2).

Two surgical chest drains were placed, and more than a litre of purulent fluid was removed. TB was diagnosed on the sputum sample, and an Acinetobacter superinfection was found in pleural effusion. After 6 months of proper medical treatment with Streptomycin, Isoniazid, Rifampin, and Pyrazinamide, the Thorax CT-scan showed a III stage chronic empyema (AATS guidelines) with major fibrothorax and entrapped lung, so pleural decortication was planned. Due to important parenchymal inflammatory damages, especially within the right upper and middle lobe, pulmonary decortication and surgical toilet with debridement of infected tissue were performed through a posterior thoracotomy. Postoperative period was characterized by incomplete lung re-expansion, persistent air-leaks and failure of pleural infection control with sepsis state. To avoid thoracoplasty, a very disabling procedure, we decided to proceed to an OWT with the resection of the anterolateral segments of VIII, IX and X ribs, allowing good exposure of the entire cavity and the underlying lung (Figures 3,4).

After 6 months of dressings with Rifampicin soaked gauzes applied three times a week, the Thorax CT-scan showed a significant pleural cavity reduction associated with an important improvement of the underlying lung conditions (Figure 5).

Once sufficient cleansing of the pleural cavity has been obtained, regardless of the persistence of the BPF, we decided to close the OWT with a myocutaneous pedicled flap of rectus abdominal muscle to obliterate the cavity and control the BPF (Video 1; Figure 6).

The myocutaneous pedicled flap was obtained dissecting rectus abdominal muscle at its pubic insertion, which was transposed to the thoracic cavity through a subcutaneous tunnel in order to fill the residual cavity and to close the BPF (Figure 7).

The postoperative period was completely uneventful and the patient was discharged in good general conditions, asymptomatic and without any sign of myocutaneous flap necrosis or rejection. On one month follow up, the patient remains totally asymptomatic, with a healed myocutaneous flap and without any sign of abdominal herniation.


The management of tuberculous empyema with pulmonary complications is still challenging. In patients with signs of infection or BPF, pleural drainage could prevent septic conditions and contralateral pulmonary aspiration. In these cases, especially when BPF is present, failure rate of conservative treatments, such as close chest drainage, is very high. Often, surgical decortication and empyemectomy are not conclusive or even feasible, and disabling surgery of the chest wall should performed.

According to AATS Guidelines, in patients with chronic empyema who are medically unfit or those patients with chronic empyema with a BPF, opening a thoracic window with marsupialization of the infected thoracic cavity with resection of several ribs and dressing changes is reasonable to be performed (LOE C) (10). Our approach is a modification of the Clagett procedure, originally described by Clagett and Geraci in 1963 (11). The 2-step Clagett procedure (without flap transposition) in the treatment of post-resection empyema is possible only in the absence of BPF. In our case, OWT was carried out according to the standard technique; the entity of rib resection was as limited as possible to ensure adequate drainage and easy changes of dressings. When local control of the infection is achieved, patients are offered OWT closure. The presence of fistula is not a contraindication for closing the window. Obliteration of the cavity by transposition of the muscle flap can be reserved to patients with persistent or recurrent BPF. The type of muscle used for transposition is decided by the size and position of the cavity, local muscle flaps are used as the tissue of choice. They are generally safe, require less operative time than free flaps, can be taken as muscle with an overlying skin paddle (12). We could not use the latissimus dorsi muscle because it was damaged and so ipovascularized during the previous thoracotomy; for these reasons, we decided to use a myocutaneous pedicled flap of the rectus abdominis muscle (Figure 8).

Figure 8 Chest X-ray showing the result of surgical treatment.

Intrathoracic muscular transposition (IMT) is used to obliterate the pleural space and, at the same time, to close a possibly associated BPF. The use of IMT could prevent recurrent BPF, based on the stimulation of neoangiogenesis of ischemic bronchial stump and could lead to lower functional damage and to cancel the residual pleural space (9).

We can conclude that the patient’s quality of life has been significantly improved thanks to our treatment.


There are several studies of OWT followed by IMT in patients with chronic empyema [e.g., (12,13) and reference therein]. However, few studies have been conducted in patients with chronic tuberculous empyema (4). Our case suggests that IMT in patients with chronic tuberculosis empyema is an effective and safe procedure to close and prevent recurrent BPFs.
